../lib/engine/dokit_binding.dart:129:12: Error: The method 'setMockMessageHandler' isn't defined for the class 'BinaryMessenger'. - 'BinaryMessenger' is from 'package:flutter/src/services/binary_messenger.dart' ('../../../../fvm/versions/stable/packages/flutter/lib/src/services/binary_messenger.dart').

报错分析： setMockMessageHandler 和 checkMockMessageHandler 方法迁移

// Looking for setMockMessageHandler or checkMockMessageHandler?
// See this shim package: packages/flutter_test/lib/src/deprecated.dart

报错分析：
方法f 类型问题
as转换
origin.authenticateProxy = f as Future Function(String host, int port, String scheme, String? realm)?;

hello，谢谢反馈的问题。这个问题有过修复，暂还未合到master分支。
1、如果您下载了工程源码的话，可以切换到feature/dev_flutter分支试一试。在这个分支上注掉了失效方法setMockMessageHandler。
2、如果使用版本方式引入dokit的话，可以将版本指向：dokit 0.8.1-nullsafety.0 试一下。
https://pub.dev/packages/dokit/versions/0.8.1-nullsafety.0
